SUPPORT FOR LIGHTING-FIXTURES.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed September 25, 1915. Serial No. 52,587.

To all whom it may concern:

Be it known that 1, MAX HERSKOVITZ, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Supports for Lighting- Fixtures, of which the following is declared to be a full, clear, and exact description.

This invention relates to electric lighting fixtures, and its primary object is to simplify, cheapen and. otherwise improve upon constructions of this class.

The invention relates more particularly to that class of electric lighting fixtures in which a support or base is employed for sustaining the remainder of the fixture, which fixtures may comprise chains, links, or bars and bowls and lamps of direct, indiroot or semi-direct lighting fixtures, or the support or base may directly support the sockets, shade holders, lamps and shades of other forms of fixtures, the socket being screwed directly into the support.

This invention has been designed to improve upon a form, common and well known to those skilled in the art to which this invention pertains, in which a pipe of small diameter is used, which pipe is screw threaded on both ends, one end being screwed into a fixed part fastened to the wall or ceiling and the other part screwed into the loop or ring from which the remainder of the fixture is sustained. For the purpose of ornamentation and finish a light weight tube (preferably of brass) surrounds the pipe, thus covering up the otherwise exposed screw threads on its ends. Such a construction not only is comparatively expensive but the parts thereof are apt to become disconnected from each other or the brass covering tube is apt to be a trifle short, conse-' tion, said View being partly in side eleva tion and partly in central vertical section. Fig. 2, is a side elevation of said support; Fig. 3, is a detail, cross section taken on line 33 of Fig. 1, and Fig. 1, is a side view, partly broken out of a slightly modified form of the invention.

Referring first to Figs. 1 to 3, inclusive, of said drawing, 10, designates an insulating member which is suitably secured to a ceiling, wall or other part of the structure upon which it is desired to mount the fixture. Said member 10, has a screw threaded socket 11, in one end for the reception of the externally screw threaded end of the fixture support 12. Obviously said member 10 may comprise any desirable attachment member having the screw threaded socket for the reception of the screw threaded end of the fixture support 12.

In the preferred embodiment of the invention the support 12, comprises a hollow body portion 18, of suitable size, preferably tubular in form, and having a reduced neck portion 14-, externally threaded and adapted to be screwed into the screw threaded socket 11, of the attachment member 10; the shoulder 15, formed between the body portion 13, and neck portion 14, being screwed up tight against the face of the member 10. The other end of the body portion 13, is formed with a connecting member 16, for attachment to the fixture members to be sustained by the support and said connecting member 16, is shown in the preferred form to comprise a ring or loop cast integral with the body 13. For the sake of appearance, and in order to simulate built up fixture supports the body portion 13, is cast with a bead 17, between the body and loop, as is clearly shown in Fig. 1, and Fig. 2 of the drawing. Preferably the body portion 13, is formed in its side near its neck, with an aperture 19, through which the conductor cords or wires 20, lead into the interior of the body and said body is also formed with an aperture 21, in the end portion which has the ring or loop cast thereon, and the electric conductor cords or wires lead out through said aperture 21, and thence to the socket or sockets of the fixture sustained by the support.

The ring or loop portion 16, furnishes the direct connection between the fixture support and the remainder of the lighting fixture sustained thereby, and, in accordance with the connnon practice said lighting fixture may be attached to the support by a ring. link or the like, linked into the ring portion 16, of the support, the electric conductor cords or wires being threaded through the rings or links of the fixture as usual.

In connection with the fixture support a bell shaped canopy 22, which has a neck portion 23, fitting loosely upon the body portion of the fixture support and having a set screw 14-, threaded therein and arranged to be screwed up against the body portion 13. biaid canopy flares upwardly as is usual and is designed to enter the threaded end and insulating member 10, thus making a finished end portion for the support, as is connnon in electric lighting fixtures.

In the modified forni shown in Fig. the body portion may be similar in all respects, if desired, to that shown in the preferred form. In this modified form a hollow ball, substituted for the ring portion, into which may be screwed the threaded necks of lamp sockets, 20, or threaded ends of posts, andards, brackets, arms or the like, for supporting one or more lainp sockets, 23. The aperture, 27, into which the socket is screwed, forms the egress opening for the electric conductors or wires which lead to the electric lain socket, 96.

From the above description and explanation it is to be observed that screw threaded connections among elements of a fixture support of the type described, are eliminated, whereby there are no individual component parts that may become unscrewed or loosencd from each other. A fixture support, embodying the present invention, is an integral unit, incapable of separation into parts; consequently, it can be sold and con- Yeniently handled as a complete article of merchandise. Furthermore, it is easily assembled with the remaining portions of the lighting fixture, and the wires may be asily and readily threaded through the one-piece support. The contour and shape of the support may be varied to suit the individual taste, and it may be otherwise ornamented and elaborated, as desired.

More or less variation of the exact details of construction shown and described, is possible, without departing from the spirit of this invention, and I desire, therefore, not to limit myself to the particular forms shown and described, but intend in the following claim to point out all the invention dis closed herein.

I claim as new and desire to secure by Let ters Patent:

As a new article of manufacture, an integral support for electric light fixtures, said support consisting of a single tubular cast ing having a screw threaded extension at one end, and a loop at the other end from which a fixture is suspended, said loop having at its top an opening con'nnunicating with the interior of the tubular body and a slot through the wall of said body, said opening and slot providing a passage for conductor cord into and out of said body.
